!!! Territorial activity observed at Hearn!!

Friday March 13th - 2015
I had an opportunity to get down to the old OPG Hearn plant on Unwin Ave this evening on my way home to check on the status of the resident Hearn peregrines, and was delighted to see at one of resident peregrine falcons on site, overlooking its domain. Actually, the adult colored peregrine was perched high up on the smoke stack, roosting on the top of the west facing white strobe light , 3/4 the way up the smoke stack.

I watched the peregrine roosting on the strobe light for approx.40 minutes after my arrival, and then watched it make an incredible dive and stoop on a large black coloured bird close to the base of the smoke stack. The peregrine dove and stooped down so fast that I couldn’t even follow it with my bare eyes, and it was only after the explosion of feathers when it hit the smaller bird, did I realize that it had come that close to the base of the smoke stack and the ground level!!. Moments later, it re-appeared back in my view against the lighter blue sky with a kill in its clutches and I watched the peregrine utilize the air movements to gain altitude as it snaked back and forth around the west side of the smoke stack finally ascending to the highest upper most white blinking strobe light (almost at the very top of the large smoke stack on the south side), where it finally landed and eventually chowed down to eat its prize!

What an incredible display of determined, focused talent!!

I finally departed at dusk when the light simply disappeared making it too difficult to see much of anything. As a foot note, I have long since forgotten just how dark it gets down there, given the lack of street lights and other ambient light that would normally come from other hi-rise buildings.

Sadly, I didn’t have my camera this go-round, but I promise that I won’t forget it next time!!!
Stay tuned,,,,,,

!!! Peter spotted and photographed out on the spit.

A big thanks to Mike for sending in some of his recent photos of Peter that he snapped of Peter while out on the spit December 27th - 2014.
Hi,
I was at the Spit on 27 Dec 2014. I went looking for the Purple Sandpiper at the end of Peninsula A but instead I found Peter the adult male Peregrine. His leg is tagged 46Y. Peter was preening the whole time I was there. He’s looking very active and healthy. Here are a few pics.

!!! Renewed nesting activity in question?

June 08, 2014 - Toronto - Hearn Power Station

CPF Postmaster Reports:

June 8th - 2014I visited Hearn today from 10:30 - 11:15 am. Neither bird visible in the area until after 11 when I noticed one perched on a pipe at the side of the building - not sure if it was the male or female. The only other thing of note was a pile of what I assumed were pigeon feathers on the ledge where I had observed the pair on Friday.

Lots of activity at the nearby Raven nest though - looks like the young are beginning to fledge.

!!! Second nesting attempt at OPG Hearn plant!

June 5th - 2014
Yesterday (June 5, 12:30 pm), I was able to observe the pair from Unwin Ave. on a possible nest site to the right of the stack. At first I could only see one bird (maybe the male?) and he seemed to be working on something - at least he seemed to be spending a lot of time with his head down. Then the second bird (who seemed a bit larger so I’m guessing female) appeared from deeper in the structure and walked past the first bird to the ledge. They remained together for several minutes before the male flew away to perch on a pipe on the side of the building (I’ve seen one perched in this same spot several times this spring). I stayed for a total of 20 minutes and neither had moved by the time I had to leave.

Here are a few photos to give you an idea what was going on - sorry for the poor quality!

Angela and Peter Appear to Have a Failed Nest

June 01, 2014 - Toronto - Hearn Power Station

Bruce Massey Reports:

I came down to Hearn Generating Station today and met up with Harry at the site to check in on the resident adults and their progress towards nesting.  When I arrived there was nobody visible.  I walked to the east and checked the back side of the stack and again saw nothing.  I moved back out front to the south side of the building and within 20 minutes both birds arrived from the south.  Peter and Angela landed on the small opening to the west of the old nest area and both disappeared into the grid work.  Angela appeared and flew up to the vent on the south side where she roosted and Peter finally emerged and had a great soar above the structure.  His flights eventually took him off to the north and out of view.

Based on these observations both Harry and I agree that they are not incubating nor brooding any young.  They seem to be interested in the south side ledges once again leading us to the conclusion that the first nest has failed and that a reclutch may follow.

We will keep you updated as we learn more.

Possible nest at the Hearn

May 06, 2014 - Toronto - Hearn Power Station

Harry Crawford Reports:

Today, I made my first trip down to the Hearn for this year.
Arriving at 9:15am, I spotted what I think was Angela - she appeared
to be nesting.  If so, the location is different than last year’s.
She was on the top level - dead centre, of the same area as last
year’s third attempt.  This is the segment just west of the old area
to the left of the stack.  I was only around for 15 minutes and she
didn’t move during that time.

A Canada goose flew in low and Peter suddenly appeared.  He flew
around a few times but disappeared to the roof area just east of the
stack out of view.

!!! Still involved in courtship! No incubation as yet!

April 12th - 2014
A quick visit to check in on the Hearn peregrines this afternoon resulted in some good observations. Both adults were quite visible and very active for the several hours that we were down at Hearn this afternoon.

Peter, the resident adult male, was still very busy courting his gal and on two occasions he brought her small food packages, followed by several rounds of copulation and mating.

During the several hours of observations, the un-banded resident adult female spent most of her time roosting on various levels of the superstructure and at no time did she give up any of her choice of potential nesting spots. Peter spent most of his free time chasing the local avian inhabitants out of the territory and tending to his courtship activities.

More time in will be the only way that we are going to find out where she has decided to lay her eggs.
Stay tuned ………………

!!! Lots of copulation going on, but no incubation observed as yet! Where will she lay her eggs???

I was able to spend several hours down at the Hearn plant on Unwin Ave this evening and spotted both the resident adults on site moments after my arrival. For the next several hours, (until 8pm and my light faded), both birds were in full view for the most parts in their usual roosting spots with multiple computations observed.

While I was unable to identify leg band numbers or colours due to the distances involved, I was able to confirm that the resident adult female is NOT banded. Sadly, the resident adult male never came lower than the mid elevation of the superstructure, and due to the poor lighting conditions, there was no way of getting close enough to him even with a 75 power spotting scope eyepiece to see if he was banded, let alone actually identifying any leg band digits.

As you can see by the attached photos of the resident adult female, both of her legs are void of any leg bands. The resident adult male of the last few years at Hearn was a Black Banded male named Peter that was produced in Hamilton Ontario, at the Hamilton Sheraton Hotel nest site. We are looking to confirm his leg band number to see if it is still Peter. He dawns a solid Black recovery band on one leg and the usual Silver USFW band on the other leg.

Throughout my observations, the resident adult male went on several hunts, and was successful on two occasions in his efforts in capturing and killing food. He brought food into the female and dined on the second kill himself.

Even after a big meal and several copulations, the female did not give up the location where she intends to lay her eggs as she was visible throughout my entire observation period.

Its going to take a few more visits and some very close observations to find out where she has decided to lay her eggs!

Egg production is close, as they are busy copulating and egg fertilization and egg laying is very close!
Looking for any and all assistance if you are down at the Hearn location to do some observations and let us know what you are seeing…..

Stay tuned, more to come………..


!!! A not so private moment at Hearn! Copulation and egg production is underway!!

Hello Guys
I witnessed this at the Hearn Generating Station on Unwin Avenue just after 1:00pm March 27th. It is a terrible photo because they were just too far away but if you can use it please feel free to.

Cheers.

!!! Spring is in the air at Hearn as Peter & Angela are once again very visible.

Hey Guys,

I just wanted to give you an update on the observations they we gathered at the old Hearn power plant. For the past week, there has been two peregrines back hanging around the plant - (most likely Angela and Peter). They were observed copulating yesterday and again today. Lets hope that they pick a good nest site this year. Talk to you soon.
